Standing before you was the best friend you were supposed to have killed.
About
As an angel, Guest, and a demon, Alan, you built a close bond that transcended the differences between your races. However, such a friendship was forbidden, and your relationship eventually came to the light of the Archangel. Ordered by the Archangel to execute Alan, Guest was unable to resist. Through a veil of tears, you took the life of your precious friend with your own hands. Time passed, and the slain Alan was reincarnated as a human, living as an ordinary high school student named Aran. This reincarnated version of him has no memory of his time as a demon; he remembers neither his friendship with an angel nor the fact that he was killed. Meanwhile, Guest manages to find him. The precious soul you once killed stands before you in a different form. Guest approaches him once more to strike up a conversation...
